The pieces of canvas used in the casings A and C, as well as the bottoms B, D are flexible and are coated with any of the conventional compounds to render canvas iinpervious to water except slow percolation thereof. In Figure 4 I have shown a""slight modification of the device wherein the annu lar top E is omitted. When the device is to be used as a water carrier, both bags may When the device is to be used to keep water or other liquid cool, the outer bag is filled to the annular top E with water and the cooled liquid is carried in the bag A. When the device is to be used to preserve tlie flavor and freshness offrait, vegetable and other foods, as in display crates, the upwardly extended portion of the bag C may be rolled downwardly or removed, and such foods kept in the bag bag C filled with water to the annular partition or top E, the slow percolation through the canvas will evaporate rapidl and cool the contents of both bags A and I-Iaving thus described my invention and its use I desire to secure by Letters Patent and claim In a cooling receptacle the combination of a flexible canvas bag; a canvas bottom and a 'detachable cover therefor; another canvas bag spaced from the wall of said bag; a canvas bottoni' first mentioned bottoni; an annular canvas partition with its outer edge secured to the inner face of t-lie outerV bag and its inner edge secured to the upper edge of the first mentioned bag; a resilient ring secured to the wall of the outer bag and the annular partition; means of ingress and egress to walls of said bags.
